Tin dioxide was modified via mechanochemical and microwave treatments in order to obtain a mesoporous structure. Samples treated in water possess a thermostable crystal and porous structure. As a result, the samples modified in this way retain a large specific surface area after the manufacture of the sensor. Microwave treatment of SnO₂ gel at 270° is more promising for the creation of sensitive semiconductor sensors.
